Active Directory and LDAP Plugin
|
|
Hello everyone,
I have been tasked with integrating our Trac installation with our Active
Directory (2008).
However, I am running into some errors that I can't quite wrap my head
around.
The errors stop when I switch group_bind to false. My reading of it is that
something is failing in the group search. Is this correct?
Curiously, this doesn't seem to be affected when I intentionally mess up my
password. I recall getting a specific error for bad credentials when I
tried a few months back, so I think it is failing before it even tries to
speak to the domain controller.
Has anyone had any recent success with AD and Trac?
The main Trac error is:
TypeError: argument 2 must be string or read-only buffer, not None
Traceback:
